To aZZ whom it may concern.-

Be it known that I, EZRA W. VAN D'UZEN, Jr., a citizen of the United States, and a resident of Newport, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Doors for Stoves or Ranges, ofwhieh the following is a specification.

This invention relates to improvements in doors for stoves or ranges, and has for its objects to provide a door of novel construction, and to provide means whereby the door, in being opened to form a horizontal shelf, is cushioned in its fall. These objects I accomplish by the construction and arrangement of parts hereinafter described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is an elevation showing my improvement applied to cook stoves or ranges, showing but a single spring on the door. Fig. 2 is a plan view of one of the oven-door plates, with a supporting-strip placed in the recess. Fig. 3 is a central eross-section'of the door. Figs. 4, 5, and 6 are modifications of my improved double recessed plate door. Fig. 7 represents a broken elevation of the lower part of the oven-door, showing the manner in which I employ two springs.

Arepresents a side plate of a stove or range, in which is an opening.

B represents the oven-door. It is formed of two sheet-metal recessed plates.

at represents the outer flanged edges of the recessed plates B. I have shown four modes of uniting these two recessed sheet-metal plates. Fig. 5 represents the common or preferred form, which shows the flanges a of one plate as being bent around, over, and lapping upon the flange a of its opposite plate, with the rivets a passing through the three thicknesses of metal, to hold the two plates firmly together. The object of bending over the metal of one flange to rest upon the other is, first, to furnish a smooth-finished edge for the door and to prevent the spreading apart of the two metal plates, and, second, to furnish a suitable rim around the edge to strengthen the door. In Fig. 4 I show the flanges a a of the same shape, around the edges of which is a U-shaped piece of metal, a, all united by supporting plate, at, which is a fiat piece of metal of the same size as the recessed plate 6, and resting between the flanges a a, to which it is united by rivets. Instead of the plate 61 for stiffening the plates of the door, a bent strip or ribbon of metal, E, having the same vertical depth and lying within the recess between the plates Z) b, as shown in Figs. 2 and 3, may be used. This stiffens and prevents the collapsing of the recessed plates. ferent methods of supporting the metal plates are not in all cases essential; but they make a much stiffer door.

A door constructed of the two recessed plates of sheet metal, b b, has several advantages over other marginally-flanged and hollow sheet-metal doors.

First. The air-space between the plates prevents the waste of heat by radiation through the door. The inside sheet being much the hottest, the recess allows the metal to contract and expand without warping the door.

Second. Alight door is provided.

Third. The rim of the door has sufficient yielding capacity to cause the door to yield to any inequalities in the face of the stove-plate surrounding the oven-opening, securing a perfect fit and seating of the oven-door upon the stove-plate, making tighter joints than could be secured by an unyielding or rigid rim or frame, to which sheet-metal plates are usually riveted.

H H represent hinges connecting the door 13 to the plate A.

D represents springs, one end of which is. attached to the door B and the other to stoveplate A in such a manner that the recoil of the spring will hold the dcorin a closed position. These springs also serve to cushion the drop of the door and prevent the hinges from being broken off when the door is opened. I have shown two springs, which are preferable in large ranges; but in an ordinary cook-stove, and with small doors, one spring will be sufficient.

These difincreasing the efiiciency of the door' and stove. v

A stove-door has heretofore been arranged to slide in hearings on a stove and subjected to the action of a coiled spring arranged at one edge of the door, for the purpose of throwing the latter to a closed position as soon as released; but such does not constitute my invention. A glass face-protector for ranges has been pivoted at its lower corners, and counterbalanced by means of weights, cords, and

- position.

pulleys; but neither does such constitute my invention. a

It will be observed that in my invention the oven-door is hinged below the oven-opening, and the spring is attached at one end to or seated against the lower portion or edge of the hinged door, while the other end of said spring is attached to the stoveplate. The effect of this arrangement and combination is such that when'the door is swung open to act as a horizontal shelf for supporting pans it is cushioned in such movement, and but little effort is required to bring it intoa horizontal At the same time the door will not be raised from a horizontal position until manipulated by the attendant, and when this is done the spring comes into active operation and aids in closing the door; and, further, when the door is closed, the tendency of the spring is to retain it in such position. It will thus be seen that the arrangement and combination accomplish important results, and are the means of rendering the range very desirable to housekeepers. By my invention I avoid the necessity of changing the construction of the range, and the improvements are capable of being applied to ranges already constructed without the application of any complicated or expensive means for attaching the spring.

I claim- 1. An oven-door for a stove or range formed of two sheet-metal plates, the bodies of which are recessed to form depressions, and their edges forming flanges united together, with the depressions in the plates opposite each other, so as to form an intervening air space or spaces between the plates, and a supporting-ribbon between the -recessed plates for strengthening the door, substantially as herein set forth.

2. In astove or range having an oven-chamber, the combination therewith of an oven drop-door, hinged below the oven-opening to the stove-plate, a spring seated at one endupon the oven-door adjacent to its lower edge, and at its other end seated upon the stoveplate below the oven-opening, for cushioning the fall of the door to a horizontal position for forming ashelf, and link-supports secured at one end to the stoveplate adjacent to the sides of the oven-opening, and at their other end connected with the door, substantially as and for the purpose described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
